Have this issue where I step on the gas lightly and nothing happens, then at about 1/4 throttle it lunges and takes off. Looking at it on the scan tool, the pedal sensor shows a perfectly smooth transition from 0-100%. The sensor called "R Throttle" whatever that is, shows 8% at idle, will move a little bit to 12%, and then during light pedal movement it will do nothing and then jump to 25 or 40%, or some other random percent in between.
Now here's the weird part- if I set the cruise control on the highway it shows the R-throttle steady around 12%. When I come to a hill then the R-throttle shows a perfectly smooth increase to about 25% while climbing the incline. But on straight level highway if I try to lightly step on the pedal, the R-throttle jumps all over the place from 20-45%. Meanwhile the actual pedal position sensor is showing a smooth reading and not jumping around.
I'm trying to figure out how the pedal is wired to everything. Since my scanner is showing a smooth transition, that should eliminate the pedal sensor and all the pedal wiring up to the computer since the computer is also forwarding that info to the live scan tool. I think the computer then sends the throttle request to the throttle body ETC motor. For some reason the ETC motor works perfectly fine with the cruise control but not from the pedal.
I'm lost as to what the problem is. Maybe the computer is screwed up. Anyone else have this problem?
